The Impact Of Computers Essays - E-commerce, Free Essays The Impact Of Computers THE IMPACT OF COMPUTERS Computer technology not only has solved problems but also has created some, including a certain amount of culture shock as individuals attempt to deal with the new technology. A major role of computer science has been to alleviate such problems, mainly by making computer systems cheaper, faster, more reliable, easier to use. Computers are forever present in the workplace. Word processors-computer software packages that simplify the creational and modification of documents-have largely replaced the typewriter. Electronic mail has made it easy to send messages worldwide via computer communication networks. Office automation has become the term for linking workstations, printers, database system, and other tools by means of a local-area network. An eventual goal of office automation has been termed the paperless office. Although such changes ultimately make office work much more efficient, they have not been without cost in terms of purchasing and frequently upgrading the necessary hardware and software and of training workers to use the new technology. Computer integrated manufacturing is a relatively new technology arising from the application of many computer science sub disciplines to support the manufacturing enterprise. The technology of CIM emphasizes that all aspects of manufacturing should be not only computerized as much as possible but also linked together via a computer communication network into an integrated whole. In short, CIM has the potential to enable manufacturers to build cheaper, higher-quality products and thus improve their competitiveness. Making a telephone call no longer should conjure up visions of operators connecting cables by hand or even of electrical signals causing relays to click into place and effect connections during dialing. The telephone system now is just a multilevel computer network with software switches in the network nodes to route calls get through much more quickly and reliably than they did in the past. A disadvantage is the potential for dramatic and widespread failures; for as has happened. The downside of this technology is the potential for security problems. Intruders can see packets traveling on a network and can perhaps interpret them to obtain confidential information. Computer technology has had a significant impact on retail stores. All but the smallest shops have replaced the old-fashioned cash register with a terminal linked to a computer system. The terminal may require that the clerk type in the code for the item; but more and more frequently the checkout counter include a bar-code scanner, a device that directly reads into the computer the UPC printed on each package. Cash-register receipts can then include brief descriptions of the items purchased, and the purchase information is also relayed back to the computer to cause and immediate adjustment in the inventory data. The inventory system can easily alert the manager when the supply of some item drops below a specified threshold. In the case of retail chains linked by networks, the order for a new supply of an item may be automatically generated and sent electronically to the supply warehouse. In a less extensively automated arrangement, the manager can send in the order electronically by a dial-up link to the suppliers computer. These developments have made shopping much more convenient. The checkout process is faster; checkout lines shorter; and the desired item are more likely to be in stock. Computer technology has been incorporated into automobiles. Computers are involved (CAD systems) not only the design of cars but also in the manufacturing and testing process, perhaps making use of CIM technology. Todays automobiles themselves include numerous computer chips that analyze sensor data and alert the driver to actual and potential malfunctions. Although increased reliability has been achieved by implementing such computerization, a drawback is that only automotive repair shops with a large investment in high-tech interfaces and diagnostic tools for these computerized systems can handle any but the simplest repairs

An Introduction to Combustion (Burning) Reactions

An Introduction to Combustion (Burning) Reactions A combustion reaction is a major class of chemical reactions, commonly referred to as burning. Combustion usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water. In the more general sense, combustion involves a reaction between any combustible material and an oxidizer to form an oxidized product. Combustion is an exothermic reaction, so it releases heat, but sometimes the reaction proceeds so slowly that a temperature change is not noticeable. Good signs that you are dealing with a combustion reaction include the presence of oxygen as a reactant and carbon dioxide, water, and heat as products. Inorganic combustion reactions might not form all of the products but are recognizable by the reaction of oxygen. Combustion doesnt always result in fire, but when it does, a flame is a characteristic indicator of the reaction. While the activation energy must be overcome to initiate combustion (i.e.:Â  using a lit match to light a fire), the heat from a flame may provide enough energy to make the reaction self-sustaining. General Form of a Combustion Reaction hydrocarbon oxygen → carbon dioxide water Examples of Combustion Reactions Here are several examples of balanced equations for combustion reactions. Its important to remember that combustion reactions are easy to recognize because the products always contain carbon dioxide and water. In these examples, oxygen gas is present as a reactant, but trickier examples of the reaction exist where the oxygen comes from another reactant. combustion of methaneCH4(g) 2 O2(g) → CO2(g) 2 H2O(g)burning of naphthaleneC10H8 12 O2 → 10 CO2 4 H2Ocombustion of ethane2 C2H6 7 O2 → 4 CO2 6 H2Ocombustion of butane (commonly found in lighters)2C4H10(g) 13O2(g) → 8CO2(g) 10H2O(g)combustion of methanol (also known as wood alcohol)2CH3OH(g) 3O2(g) → 2CO2(g) 4H2O(g)combustion of propane (used in gas grills and fireplaces)2C3H8(g) 7O2(g) → 6CO2(g) 8H2O(g) Complete Versus Incomplete Combustion Combustion, like all chemical reactions, does not always proceed with 100% efficiency. It is prone to limiting reactants the same as other processes. So, there are two types of combustion you are likely to encounter: Complete Combustion - Also called clean combustion, clean combustion is oxidation of a hydrocarbon that produces only carbon dioxide and water. An example of clean combustion is burning of candle wax, where the heat from the wick vaporizes wax (a hydrocarbon), which reacts with oxygen in the air to release carbon dioxide and water. Ideally, all the wax burns so nothing remains once the candle is consumed. The water vapor and carbon dioxide dissipate into air.Incomplete Combustion - Also called dirty combustion, incomplete combustion is hydrocarbon oxidation that produces carbon monoxide and/or carbon (soot) in addition to carbon dioxide. An example of incomplete combustion would be burning coal, where a lot of soot and carbon monoxide is released. Many of the fossil fuels burn incompletely, releasing waste products.

The Milgram experiment - Essay Example This particular aspect also contravenes ethical principal A: Beneficence and Nonmaleficence ("Ethical Principles", 2003). However it should be commended that when offering payment of $4.50 an hour, the participants were told that they would receive the payment whether or not they completed the experiment, this was the most ethical thing to do as then payment wouldn't be the motivator of the participants actions. Looking at all the facts given above, it can be argued that the researchers should have been honest with the participants about the nature of the experiment being a study in obedience and not that of memory and learning and that the experimenter should have reminded the participant/teacher that they are free to leave at anytime, instead of using verbal prods to ensure they continue with the experiment. While this is correct we should keep in mind that the experiment results would not have been accurate if the above suggestions were followed even though it may have made the experiment more ethical.

Passage Analysis - Essay Example Poe then allows the reader to imagine what the rest of the "evidence" is on "her emaciated frame". It is as if the reader is seeing her for the first time along with the characters. She is just a "frame" rather than a body, seeming more dead than alive and more terrible in her aspect because of it. The use of the verbs "trembling" and "reeling" evokes the physicality of her precarious predicament, again making the reader actually see the woman with his/her mind's eye as they are reading. The sentence structure here copies the moment of suspense that the characters are going through. The ",then," reflects the uncertainty as to what is about to happen for the narrator. Will she fall outwards or inwards or will she stay trembling, caught between the two The rest of the sentence answers this question. A first year English student might be accused of writing a "run-on" sentence if she handed this in, proving that the 'rules' of grammar are in fact merely conventions that can and should be broken when needed. As the woman is in her final "death-agonies" it is her brother who is taken "to the floor a corpse". Poe brilliantly evokes the terror and suddenness with which the brother dies.

Market Based Accounting Research Impacts

Market Based Accounting Research Impacts Market-based Accounting Research Introduction Accounting provides financial data about the performance of a company. This data enables accounting information users, including investors, to take their decisions about investing in the shares of a company. Similarly, accounting research evaluates the usefulness of this accounting data to investors and other users. The relationship between the two can be examined through market-based accounting research. Market-based accounting research is a search into relationship between publicly disclosed accounting information and the consequences of use of this information by equity investors. In other words, market-based accounting research examines the association between accounting numbers and security return and tests whether or not accounting data carry any information content to security market. Rationale for the Research Market-based Accounting Research is extremely relevant to the study of capital market efficiency, CAPM, information economics and regulation. The main drive of market-based accounting research comes from major developments in finance theory during the last few decades, especially in late 50s and early 60s. These developments include portfolio selection theory, Capital Asset Pricing Model (CAPM), and the concept of information-efficient capital markets followed by developments in information economics, agency theory and optimal incentive-signaling models. The rationale of this study has its basis in the research in this area in the past. Over the past three decades, a significant amount of research in market-based accounting research has emerged to evaluate the usefulness of accounting data to investors and the association between the accounting numbers and security return. In fact in the recent years due to development of capital markets, globalization and increase in stock trading, market-based accounting research has become even more important. Contemporary market-based accounting research has primarily focused on its international dimension which has had important policy implications for regulators and others who deal with disclosure requirements in different stock exchanges. The focus of this dissertation will be on examining how market-based accounting research impacts the kind of common stock traded in major stock exchanges. In light of this, the study will examine the relationship between accounting numbers, stock market returns and market valuations. Key Aims Objectives As indicated above, the prime focus of the study is to examine contemporary accounting theory and research with an emphasis on market-based accounting research and its impact on capital markets. As market based accounting research is based on the valuation of firms and their securities, the use of financial statements for valuation purposes, and the implications for financial reporting and corporate governance, all these areas will form a part of this study. The study aims to: Describe the concept of market based accounting research Identify the information content of market-based accounting research Provide an insight into local market conditions as well as comparative international state of market-based accounting research. Examine the role of market-based accounting research and the importance of disclosure of accounting information on capital markets Examine how published information is used by investors for designing their trading strategies Describe how market-based accounting research information impacts the capital markets efficiency Describe accounting based valuation and relate it to the content of brokers’ reports Key Research Questions The three key research questions proposed to be examined by this study are: What is the role of accounting information in capital markets? What is the information content of accounting information? What is the market-based accounting research hypothesis in context of influence on investors investing in stocks? Another key research question is how the market reacts to reported earnings, as well as the impact of reported earnings on the properties of analysts’ forecasts. These questions, especially the information content of accounting information, can be measured by the influence of the information on security prices. While measuring the influence it is assumed that investors can understand the differences in earnings that are due to differences between accounting methods. In other words, the study is based on efficient market hypothesis or the assumption that stock prices accurately and quickly adapt to all available information and therefore prevent individuals from getting abnormal return. Proposed Research Methodology Sources of Data / Information The study will be both exploratory as well as descriptive and will rely on both primary as well as secondary sources of information. Sampling for Primary Information Primary data will be collected from a sample consisting of both brokers as well as individual and institutional active investors who have invested in equity shares in a few pre-selected companies listed on the US or European stock exchanges. The period of investment will be from 2000-2006 as 6 years is a sufficient time to analyse the impact. These investors will be chosen on the basis of the frequency with which they invest in the securities. Data will be collected by administering questionnaires seeking information on how these investors make an investment decision. Sources of Secondary Information The prime source of secondary data will be: Annual reports of the selected companies under consideration. The variables that will be focused upon will include stock returns, dividends, net income on sale, return of equity, return on asset, debt ratio, interest coverage, current ratio, Price-earning ratio and price. The final report will be supplemented with information from: Literature searches ( refer list of references at the end of the document ) Past articles and research in the area Internet searches: Searching specific data from Yahoo and Google search engine Data Analysis Data will be compiled into data master sheets. The statistical description for all the variables will be presented in a separate table. The various sets of information pooled over the five year period of study will be clearly presented in the table in context of the various variables. The standard deviation and also correlation between the variables and the stock return will be determined and analysed. Correlation will be based on Karl Pearson’s method of correlation. In addition to standard deviation and correlation, regression analysis will also be used for examining the market reaction to reported accounting information. Regression is used for analysis of impact of independent variables on the dependent variable. The dependent variable for regression analysis will be stock returns while the independent variables will be dividends, Net income on Sale, return of equity, return on asset, debt ratio, interest coverage, current ratio, and price-earnings ratio. Regression equations will be solved using Ordinary Least Square method (OLS). Qualitative data gathered from the investors may include opinions of respondents on a certain issues, reasons for certain behaviour and descriptions of certain procedures, practices or perceptions with which the researcher is not familiar. The data can be analysed by classifying all answers into a few categories. References Abeyratna, G, A.A.Lonie, D.M. Power and C.D.

LAN Based Inventory System Essay

1 INTRODUCTION 1.1 Background of the Problem Nowadays, computerized system is the main tool that will help to lessen the work and improve data integrity. Working in a company that has no system takes a lot of time and effort to retrieve the data that they want because the large part of the process of the business is manual. MIS (Management Information System) Office is divided into three (3) sections: Systems Development and Administration Section, Network and Technical Maintenance Section, and Education and Training Section. The project will only focus on one of the three sections, which is the Network and Technical Maintenance Section. . MISO caters their services and requests to other Local Government Offices and National Agencies within the Pasig City Hall. Some of these departments and offices are the License Office, Treasurer’s Office, Accounting Office, National Statistics Office (NSO), etc. Network and Technical Maintenance is having a hard time in keeping their records since all of it is written down on paper. Whenever they need to look for a specific report, they would have to go through the pile of service records in the office. This consumes too much time. All requests for peripheral devices, such as printers, keyboards, and monitors, are in the form of a letter, and all requests for services like troubleshooting and installation will either be in the form of a letter or a phone call. The Network and Technical Maintenance Section mostly considers the allocation and monitoring of peripheral devices as their major problem in the office. Technicians cannot define clearly whether a specific peripheral device is lost, damaged, for disposal, etc. 1.2 Overview of the Current State of the Technology MIS Office is responsible for research, development, implementation and management of integrated computerized application system of the city government. It is in-charge of providing technical information and education  to the city government employees and its constituents of all barangay through the Computer Literacy Programs. The office is responsible for maintaining the existing data network communication in different offices where the computerized system are installed and used, and updates/coordinates with the contractor of the Network Installation for troubleshooting and preventive maintenance. It is also in-charge of evaluating, monitoring and maintaining all computer equipment and directs the utilization of Information Technology (IT) in the different government operation of Pasig City. The department that needs to request a peripheral device is required to provide a letter of request to the Head of MIS office. If the Head of MIS office approved their request, the technician will check if the devices are available and if so, the technician will record and deploy the devices on the designated office. Network and Technical Maintenance Section is only authorized to do all the technical support. If they are going to deploy a device, they have to record to the inventory the peripheral device that they pulled-out. By recording the device, they have to write on the log book all the information needed like type of peripheral device, serial number, name of office, borrowed date, name of technician in-charge, and remarks. To do technical service, the department that needs technical support will call to MIS office and request a technician. The technician should have the service slip before they go to the other department. If the problem can be fixed within the office, the technician will fill-up the form and indicate what they have done. The employee who requested for support will confirm and sign in the service slip. But if it cannot be fixed within the area, the device will be pulled-out to the designated office and will be brought to the MIS office. After bringing the device to the MIS office, the technician will record or log in the information of the peripheral device on the log book and if the device is already fixed, the technician will log-out or return the device to the office.

The Most Important Values That I - 1494 Words

IA. The most important values that I identify with most is dedication, improvement, empowerment, empathy, and compassion. †¢ I would say that these are most important to me because without these five elements I would not be the person I am now. I wouldn’t have gotten through my struggles without being either taught or simply observing from others how you should be in life. o Dedication has been taught to me from my family; if you were to say you were going to do something, they expect you to follow through with that actions. Always stay dedicated to others because you never know when you will be in need. With dedication comes loyalty and respect. Not only be dedicated to others but yourself as well, I was always taught to stay in school, don’t give up, keep your head up, and never say â€Å"I can’t†.
